Intro/Chapter One

After Ahsoka's trial, she decides to stay instead of leaving and in that time Ahsoka becomes a Jedi Master; and so does Anakin. Obi-Wan gains a new Padawan who looks familiar to Anakin. How does he know her? How does she know him? Or do they not know each other at all and someone else is behind their connection?
*Spoiler warnings for those who have not seen The Last Jedi* Maybe their connection was made by someone evil, such as Supreme Leader Snoke?
